They were on their own -- three kids and one giant chicken. Stuck in Hoboken for the summer, Nick Itch, Loretta Fischetti, and Bruno Ugg are really, really bored.

When a mysterious and brilliant chalk artist starts decorating Hoboken's streets, the three friends are blown away. They set off to explore the art world in a frenzy of adventurous drawing, screeving, and eggplant picnics.
